Cloud Migration
Definition
Cloud migration is the process of moving applications, data, and IT infrastructure from on-premise servers or legacy hosting to a cloud platform such as AWS, Microsoft Azure, or Google Cloud Platform. It includes re-hosting (lift-and-shift), re-platforming, re-architecting, and hybrid approaches.
In Detail
For DACH enterprises, cloud migration addresses key challenges: ageing on-premise infrastructure, rising maintenance costs, limited scalability, and disaster recovery gaps. A well-executed migration reduces infrastructure costs by 20-40%, improves uptime, and enables modern capabilities like auto-scaling, containerisation, and serverless computing. GDPR compliance remains critical — data residency in EU regions (Frankfurt, Zurich, Vienna) ensures regulatory adherence.
Business Use Case
A healthcare provider in Salzburg needed to migrate patient records from an ageing Windows Server cluster to a GDPR-compliant cloud environment. Dev House Austria designed a phased migration to AWS (Frankfurt region), implementing encrypted storage, automated backups, and role-based access. The migration reduced infrastructure costs by 35% and improved system availability from 99.5% to 99.99%.
